Description

TECHNICAL FIELD

[0001] The present application relates to the field of air conditioning technology, in particular to an air conditioner outdoor unit dust removal system and an air conditioner adopting the same. BACKGROUND

[0002] Air conditioners have become an essential device in people's lives. While air conditioners bring coolness, dust in the air has become an unavoidable problem affecting the operating efficiency of air conditioners.

[0003] After long-term operation of the air conditioner outdoor unit, the heat exchange fins of the outdoor unit will accumulate a thick layer of dust, which not only affects the operating efficiency of the outdoor unit, but also affects the heat exchange performance of the fins, and will gradually increase the power consumption of the outdoor unit during operation. Users will intuitively feel that the air conditioner is becoming more and more power-consuming, which will bring many negative effects to the users.

[0004] In terms of removing dust from the outdoor unit, the traditional general method is to use external equipment to directly remove dust from the fins through mechanical vibration or spraying operation. This dust removal method not only consumes additional power, but also causes unnecessary damage to the fins during the dust removal process, such as loosening the engagement of the fins and fin tubes caused by mechanical vibration, which reduces the heat transfer performance of the fin structure to some extent.

[0005] The prior art discloses an air conditioner condenser self-cleaning system, a control method and an air conditioner. An electrostatic dust removal device is arranged at the air inlet of the air conditioner outdoor unit and is electrically connected with a controller. The electrostatic dust removal device includes a plurality of electrode plates arranged in parallel, and a resistor connected between adjacent electrode plates. The interval between the two adjacent electrode plates is equal, and the interval forms a channel for gas flow. The direction of the electrode plate is parallel to the direction of the gas flow. It uses the electrostatic field formed between the electrode plates to first remove dust from the air that will pass through the condenser fins, and then uses the reverse rotation of the fan to blow off the dust accumulated on the condenser fins and the electrode plates after the machine is turned off to achieve secondary dust removal. The above method of removing dust from the outdoor unit mainly uses static electricity to remove part of the dust in the air to purify the air to the fins, reduce the dust accumulation process of the fins, and then use the positive pressure wind provided by the fan to blow off the dust accumulated on the fins and the electrode plates. Although this method can eliminate the damage to the fins caused by mechanical vibration and spraying dust removal, the electrostatic dust removal device itself will gradually accumulate thick dust after long-term use. At the same time, it is difficult to blow off the dust accumulated on the electrode plates of the electrostatic dust removal device by the positive pressure wind provided by the fan reverse rotation. Therefore, after long-term use, if the electrostatic dust removal device is not cleaned, the dust removal rate will be significantly reduced, the problem of too fast dust accumulation on the fins cannot be solved well in the later period, the long-term efficient operation of the outdoor unit cannot be guaranteed, and the electrostatic dust removal device receiving power from the controller and relying on the fan reverse rotation after the machine is turned off will also consume additional power. SUMMARY

[0006] One of the purposes of the present application is to design an air conditioner outdoor unit dust removal system and an air conditioner to solve the problem of consuming extra electric energy in the outdoor unit dust removal process.

[0007] The present application is realized by the following technical solutions:

[0016] The present application also provides an air conditioner comprising the above air conditioner outer casing dust removal system.

[0017] The present application also provides an air conditioner outer casing dust removal method, which uses the above air conditioner. When the air conditioner is running, the electrostatic generated during the operation of the outdoor unit is collected by the electrostatic collection circuit and stored in the capacitor. The electrostatic dust accumulation structure is powered by the capacitor to generate an electrostatic field to attract some dust carried by the airflow moving towards the condenser.

[0018] The present application also provides another air conditioner outer casing dust removal system based on the above air conditioner outer casing dust removal system, which further comprises a liquid storage container and a water outlet structure.

The water outlet structure has a plurality of water outlet holes located directly above the electrostatic dust accumulation structure, and the water discharged from the water outlet holes can drop onto the top of the electrostatic dust accumulation structure.

[0019] With the above arrangement, the air conditioner outer casing dust removal system can also use the condensed water generated during the operation of the air conditioner to clean the electrostatic dust accumulation structure without relying on external power supply. This can better maintain the cleanliness of the electrostatic dust accumulation structure and make it run efficiently for a long time.

[0020] Further, in order to better realize the present application, the input end of the electrostatic collection circuit is connected to the outer casing.

[0023] With the above arrangement, the electrostatic on the outer casing is collected by the electrostatic collection circuit into the capacitor, so that the outer casing will not attract a large amount of dust due to electrostatic.

[0024] Further, in order to better realize the present application, the following arrangement is adopted: the controller is further connected with a water level sensor, the water level sensor is used to detect the real-time water amount in the liquid storage container and can transmit the real-time water amount to the controller, and the controller controls the water inlet valve to open when the real-time water amount is lower than the preset lower limit water amount or controls the water inlet valve to close when the real-time water amount reaches the preset upper limit water amount.

[0025] With the above arrangement, the controller can control the water inlet valve to open to supplement the water amount in the liquid storage container in time when the water amount is insufficient.

[0026] Further, in order to better realize the present application, the following arrangement is adopted: the controller is further connected with a delay self-start detector, the delay self-start detector is used to detect the time interval between the opening of the liquid outlet of the liquid storage container twice and transmit the detected opening time interval to the controller, and the controller can control the water inlet valve to open when the time interval between the opening of the liquid outlet twice exceeds the set time interval of the controller.

[0027] With the above arrangement, the arrangement of the delay self-start detector can ensure that the electrostatic dust collection structure is cleaned once in a certain time interval.

[0041] Embodiment 1:

[0042] An air conditioner outdoor unit dust removal system can make full use of static electricity generated during the operation of the outdoor unit to remove dust without consuming additional electric energy, as shown in Figure 1 、 Figure 2 The structure is specially set as follows:

[0043] In this embodiment, the air conditioner outdoor unit dust removal system comprises an outdoor unit, an electrostatic dust accumulation structure 4, a capacitor 5 and an electrostatic collection circuit 6.

[0044] The outdoor unit comprises an outdoor unit housing 1 and a fan 2 and a condenser 3 installed in the outdoor unit housing 1.

[0045] The electrostatic dust accumulation structure 4 is arranged in the outdoor unit housing 1 and has a setting gap with the outdoor unit housing 1 without being in contact, and also has a setting gap with the condenser 3 without being in contact; as shown in Figure 1 The electrostatic dust accumulation structure 4 and the fan 2 are located on opposite sides of the condenser 3, and when the outdoor unit is normally operated, the fan 2 operates to suck air into the outdoor unit housing 1 and then through the condenser 3 fins after passing through the electrostatic dust accumulation structure 4. The electrostatic dust accumulation structure 4 adopts all known structures in the prior art, which has the ability to generate an electrostatic field after being electrified, and has a flow channel for airflow to pass through. In this embodiment, the electrostatic dust accumulation structure 4 can be composed of multiple electrode plates vertically arranged around the main shaft of the fan 2 and arranged vertically side by side, the spacing between adjacent electrode plates is equal and forms a flow channel, and the flow channel is horizontally directed to the condenser 3, so that the airflow can flow towards the condenser 3.

[0046] As shown in Figure 2 , the two poles of the capacitor 5 are connected to the electrostatic collection circuit 6 and the electrostatic dust collection structure 4 through the circuit. The input end of the electrostatic collection circuit 6 is connected to the outdoor unit shell 1 and the electrical box, for collecting the static electricity generated during the operation of the outdoor unit and delivering the collected static electricity to the capacitor 5 with appropriate capacity for storage. The capacitor 5 is connected to the electrostatic dust collection structure 4 through the circuit, for delivering the stored electric quantity to the electrostatic dust collection structure 4 to generate an electrostatic field.

[0047] As shown in Figure 2 , an insulating layer 8 arranged with insulating material is arranged between the gap between the electrostatic dust collection structure 4 and the outdoor unit shell 1. The insulating layer 8 insulates and separates the electrostatic dust collection structure 4 and the outdoor unit shell 1, forming an independent dust absorption area on the inner side of the insulating layer 8, ensuring better dust absorption efficiency.

[0048] The air conditioner outdoor unit dust removal system collects the static electricity generated during the operation of the outdoor unit by the electrostatic collection circuit 6 and stores it in the capacitor 5, and then delivers it to the electrostatic dust collection structure 4 through the capacitor 5 to generate an electrostatic field to adsorb the dust carried in the airflow, slowing down the dust accumulation speed of the condenser 3 fins. Since the electrostatic source of the electrostatic dust collection structure 4 comes from the static electricity generated during the operation of the outdoor unit, the air conditioner outdoor unit dust removal system does not need to be driven by an external power source during normal operation, and can complete the outdoor unit dust removal work without consuming additional electric energy. The static electricity on the outdoor unit shell 1 and the electrical box is collected by the electrostatic collection circuit 6 into the capacitor 5, so that the outdoor unit shell 1 and the electrical box will not adsorb a large amount of dust due to static electricity, and the cleanliness inside the outdoor unit shell 1 can be maintained.

[0049] In view of the possible situation that the electric quantity of the capacitor 5 is too low, in order to ensure that the electric quantity of the capacitor 5 is always above the minimum limit during the operation of the outdoor unit, the capacitor 5 is connected to the monitoring and power supplementing device 7. The monitoring and power supplementing device 7 uses existing devices and has the ability to detect the electric quantity of the capacitor and the ability to charge the capacitor when the electric quantity of the capacitor is too low. The monitoring and power supplementing device 7 is connected to an external power source for use. When the outdoor unit is operating, the monitoring and power supplementing device 7 monitors the capacitor 5, and when it detects that the electric quantity of the capacitor 5 is lower than the set value, it will start to supplement power to the capacitor, wherein the set value refers to the minimum electric quantity that enables the electrostatic dust collection structure 4 to generate an electrostatic field that can provide dust removal effect for air with a certain flow rate. The monitoring and power supplementing device 7 can supplement the electric quantity of the capacitor 5 in time when the electric quantity is too low, ensuring that the electrostatic dust collection structure 4 always works normally, thereby ensuring the long-term and efficient operation of the outdoor unit.

[0050] Example 2:

[0051] This embodiment is further optimized on the basis of embodiment 1, can clean the electrostatic dust structure, maintain its dust removal efficiency, can effectively solve the problem of dust accumulation of outdoor unit fin too fast, especially adopt the following setting structure:

[0052] In this embodiment, the air conditioner outdoor unit dust removal system is provided with a water washing device, which comprises a liquid storage container 9 and a water outlet structure 10.

[0053] The liquid storage container 9 is set as a tank, which has a liquid inlet at the top for collecting condensed water, and a liquid outlet at the bottom for discharging condensed water.

[0054] The water outlet structure 10 adopts a spray pipe with closed end, and its starting end is set as a liquid inlet. A plurality of water outlets arranged in sequence along the axis are arranged at the bottom of the middle section of the water outlet structure 10.

[0055] As shown in Figure 3 The liquid inlet of the water outlet structure 10 is connected with the liquid outlet at the bottom of the liquid storage container 9 through pipeline. The water outlet structure 10 is arranged below the liquid storage container 9 and above the electrostatic dust structure 4, and the water outlets of the water outlet structure 10 are located directly above the electrostatic dust structure 4 and vertically downward, so that the water discharged from the water outlets can drop to the top of the electrostatic dust structure 4.

[0056] In use, it needs to be connected with the indoor unit, so that the liquid storage container 9 is connected with the condensed water collecting tray of the indoor unit, and the condensed water can flow into the liquid storage container 9 for collection.

[0057] In addition to the air conditioner outdoor unit dust removal system can use the electrostatic generated during the operation of the outdoor unit to pre-clean the air passing through the condenser 3 fin, but also can use the condensed water generated during the operation of the air conditioner to clean the electrostatic dust structure 4 adsorbed with dust, can better maintain the cleanliness of the electrostatic dust structure 4, so that it can run for a long time. High efficiency. When the air conditioner is running normally, it does not rely on external power supply and water source, but uses two byproducts generated during the operation of the air conditioner, electrostatic and condensed water. Electrostatic is used to generate electrostatic field of electrostatic dust structure 4 to remove dust, and condensed water is used to clean electrostatic dust structure 4. When cleaning, the gravitational potential energy of condensed water is used to clean the electrostatic dust structure 4.

[0058] In order to obtain a better cleaning effect, the overflow self-opening device 11 can be installed at the liquid outlet of the liquid storage container 9 to control the opening time of the liquid storage container 9. The overflow self-opening device 11 can be a float ball valve or other device that can open the liquid outlet when the water reaches a certain height. The overflow self-opening device 11 installed in the liquid storage container 9 controls the water outlet time, which can collect enough water after the air conditioner runs for a period of time to clean the electrostatic dust structure 4, and can ensure that the dust on the electrostatic dust structure 4 is cleaned in time and efficiently under the condition of ensuring the dust removal effect.

[0059] In view of the possible insufficient water in the liquid storage container 9, which is not enough to open the liquid outlet to clean the electrostatic dust structure 4, in order to clean in time when needed, a water inlet valve 12 is installed on the liquid storage container 9. In use, the water inlet valve 12 needs to be connected to an external water source such as tap water for use, so that when the liquid storage container 9 is insufficient and the electrostatic dust structure 4 must be cleaned, the water inlet valve 12 is opened to supplement water to the liquid storage container 9 using an external water source, and after a certain amount of water is supplemented, the overflow self-opening device 11 opens the liquid outlet of the liquid storage container 9 to clean the electrostatic dust structure 4.

[0060] In order to ensure a shorter cleaning period and to achieve automatic water replenishment, a water level sensor 13 and a controller 14 are provided in the water washing device. The water level sensor 13 is connected to the controller 14, and the controller 14 is connected to the water inlet valve 12 to control its opening and closing state. The water level sensor 13 is used to detect the real-time water volume in the liquid storage container 9 and can transmit the real-time water volume to the controller 14. The controller 14 can control the water inlet valve 12 to open when the detected real-time water volume is lower than the preset lower limit water volume, or to close when the detected real-time water volume reaches the preset upper limit water volume, so as to achieve automatic and timely water replenishment.

[0061] In order to ensure a certain cleaning period in the case of insufficient condensate water production, a delay self-opening detector 15 connected to the controller 14 is also provided in the water washing device. The delay self-opening detector 15 detects the time interval between the opening and closing of the liquid outlet of the liquid storage container 9 in a time period. When the time interval exceeds a certain period of time, the controller 14 determines that the dust on the electrostatic dust structure 4 has exceeded the light dust level and needs to be cleaned in time. When the time interval between the two openings exceeds the set time interval of the controller 14, for example, when the liquid outlet of the liquid storage container 9 has not been opened for the second time or the water outlet structure 10 has not been detected to have water flowing out for more than four days, the controller 14 will control the water inlet valve 12 to open after receiving the signal feedback from the delay self-opening detector 15, so as to supplement the water in the liquid storage container 9 to the water volume that the overflow self-opening device 11 opens, to ensure that the electrostatic dust structure 4 is cleaned once in a certain time interval.
